I run Roundcube webmail on my VPS. At the moment, it is only accessible from one virtual server hosted on the server, unless a separate Roundcube installation is created for other virtual servers. I would like to be able to make webmail available from any domain/ virtual server that I host, just by adding /webmail to the end.

I'm sure Apache must allow me to do this - only problem is, I don't know how!

Thanks - so whereabouts do I put that line? Does it go in the httpd.conf file? Is there not a way to do it automatically, so there's no need to insert the line manually for each new virtual server? And yes - quite like Roundcube! Better than Squirrelmail, anyway.

You would put that line in to a .htaccess file. There is another way which I've updated the answer to show, you would put that in to your vhosts file.

Annoyingly, I've had problems with Cloudflare, so I haven't been able to set any additional domains to try this out! Hopefully they'll iron out shortly and I'll pop back with the outcome of trying out what you mention.
